Abstract: Animal slurry has recently experienced a renaissance as organic nitrogen (N) fertilizer because, on the one hand, sustainable organic farming is receiving growing attention in order to protect the environment and, on the other hand, increasing livestock farming produces large amounts of animal manure that should be properly disposed of to avoid further environmental pollution. However, it should not be neglected that the application of animal slurries may also have negative effects, such as N losses and N contamination, especially in areas with intensive livestock production. Although there are strategies available to reduce N losses from single pathways, such as ammonia (NH3) loss or nitrate (NO3-) leaching, these strategies are not widely used by farmers due to increased costs or the potential for increased N losses from other pathways. High-carbon organic soil amendments (HCAs) with large C:N ratio have shown great potential in reducing N losses and increasing the N retention capacity of the soil. The aim of this thesis was to analyze the combined effects of treating slurries with various HCAs under different conditions after application to soil.
